AUGUSTUS IBOWSER, OF FOBT WAYNE, INDIANA. CONTROLLING MECHANISM FOR LIQUID-DISPENSERS.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed April as, 1919. Serial No. 298,280.

This invention relates toimprovements in controllin mechanism for liquid dispensers, particular y of the type of that disclosed in my previous application for liquid dispensing apparatus filed October 4, 1918,

Sr. N 0. 256,7 95, and the object of the present invention is to provide means for operating simultaneously a valve that controls the passage of liquid through the feed pipe of the dispenser and an electric switch that controls the means of su which passes through l t e feed-pipe, and also to construct theapparatus as to admit of adjustment of the several-operatingparts to insure proper simultaneous operation of the valve and switch.

The objects of the invention are accom: plished by the construction illustrated in the accompanying drawings in which igure 1 is a transverse vertical section of a part of a dispenser showing the valve and switch and also the adjustable arms respectively in operative relation therewith;

Fig. 2 is a transverse section of Fig. l on the line w-w of thereof;

Fig. 3 is a vertical elevation of Fig. 1 in a plane at right angles thereto and partly in section; and I Fig. 4 is a vertical elevation of the admission valve for controlling the passage of liquid through the fed-pipe.

Similar characters of reference indicate correspondin parts throughout the several views and re erring now to the same:

1 is the supporting stand of a dispensing head through which a feed-pipe 2, drainpipe 3 and electrical conduit 4 extend. The

feed=pipe has connection at its lower end with a source of liquid under pressure and at its upper end with a suitable dispensing receptacle and the feed-pipe is used for filling the receptacle; connection with the lower end of the receptacle and its lower end has connection with the reservoir in which the liquid is stored; and the conduit contains the electrical conductors 5 which lead to apparatus that govill -connections.

spring 10 contained therein.

cated below the plying the liquid the drain-pipe 3 has erns the supply of liquid under pressure to the feed-pipe. The receptacle, apparatus for. supplying liquid to the feedpipe are not herein shown, but are of the character disclosed in my cation above referred to.

Interposed in the feed-pipe 2 is a -T-conprevious appli- I reservoir and nection 6 and also in the drain-pipe 3 is nterposed a similar T-connection 7, the latter having projecting. lugs 8, and a by-pass valve 9 has communlcation with each of the The bypass valve is normally held in closed posltion by means of a The feed-pipe has also an interposed inlet valve 11' o- T-connection 6 for controlling the flow of liquid through the feed-pipe into the dispensing receptacleJ I In the lugs 8 'o nthe T-connection 7 is mounted an oscillating shaft 12 that is held in adjusted positions vertically by jam-nuts 13, and on the extending lower end of the shaft 12 are adjustably mounted extending arms 14 and 15 respectively. The arm 14 is positioned so as to actuate an electrical switch 16 thatis supported by-the conduit 4 and wired in connection with the conductors 5, the arm 14 bein adapted to move the push-button 17 of the switch inwardly when the shaft 12 is oscillated and thus close the electrical circuit. The arm 15 is positioned so as to bear against the stem 18 of the inlet valve as it is moved inwardly and thus open the valve which permits the passage of liquid through the fed pipe into the dispensing receptacle, and also as the lever is moved the shaft 12 is correspondingly turned in the lugs which causes the arm 14 to. close the switch 16.

hesupporting stand 1 has a chambered shut, there being a bearing bracket 27 on V the inner face of the door that bears against the outer end of the pin and moves it inwardly against the Valve stem so as to actuate the valve as the door is closed.

connected remains closed only The valves 9 and 11. are each of the type shown in Fig. 4 of thedrawings and are adapted to automatically close because of the action of the spring when pressure is removed from their stems. The switch 16 is of the push button type that normally and the circuit in which it is during the time pressure is maintained against its stem 17.

In the operation of the invention the door 22' is opened thus exposing the push button 23 and releasing pressure against the remains open,

. stem 25 so that the by-pass valve permitted to close which prevents liquid in the feed pipe from passing into the drain pipe.

When the operator applies pressureto the push button 23 the arm 15 is moved inwardly against the valve stem 18 thus opening the inlet valve 11 which permits the. passage of liquid in the feed pipe into the the switch and the opening of the inlet valve 11 may be made-to occur simultaneously so that the liquid will be admitted through the valve at the same time pressure is applied to it to cause it to flow therethrough.

What I claim is '1. In apparatus of the class described having a feed pipe provided with an inlet valve and an electric switch adapted to close an electrical circuit that governs the supply of liquid to the feed pipe, two relatively adjustable arms pivotally supported, one of which is adapted to actuate the switch and the other being adapted to actuate the inlet valve, and being adapted to close the switch and open the valve simultaneously, and means for operatively moving the arms.

2. In apparatus of the class described having an electric switch and an inlet valve; an oscillating shaft; two arms independently and adjustably mounted upon the shaft, one of said .arms being adapted to actuate'the switch and the other the inlet valve; and

means for operatively imparting movement to the arms. I

In testimony whereof I afiix my signature, in presence of two witnesses.

AUGUSTUS BOWSER.
